Description

Technical Field

[0001] The invention relates to the technical field of agricultural technology, and more particularly to a parasitic wasp releasing device and a releasing method. Background Art

[0002] Parasitic wasps such as trichogrammatids and flat-bellied wasps have been widely used in biological control of agricultural and forestry pests. These parasitic wasps usually reproduce by replacing host eggs, such as trichogrammatids reproduce by rice moth eggs, wheat moth eggs or tussah silkworm eggs, and flat-bellied wasps reproduce by tussah silkworm eggs or ricin silkworm eggs. The bred parasitic wasps are released into the field only when they are about to hatch in the host eggs. The existing release devices include spherical releasers (for example, application number: 201721374430.5, patent name: a trichogrammatid spherical releaser), paper card releasers (for example, application number: 201721374430.5, patent name: a trichogrammatid spherical releaser), and paper card releasers (for example, application number: 201721374430.5). : 200920055761.1, patent name: Flat-bellied Wasp Reproduction Release Card), bag-type bee releasers (for example, application number: 98239636.8, patent name: Trichogrammatid bag-type bee releaser) and box-type bee releasers (for example, application number: 200620029161.4, patent name: Trichogrammatid box-type bee releaser), etc. These release devices are used to load host eggs parasitized by parasitic wasps. When used, the host eggs parasitized by parasitic wasps are placed in the bee releaser or glued to paper cards and released into the field before the bees emerge.

[0003] Existing release method all is to release before parasitic wasp does not emerge, at this moment bee is in host egg, parasitic wasp in some release devices cannot escape when being attacked by other organisms, host egg used by numerous bees such as rice moth egg, wheat moth egg field is susceptible to ant, spider etc. feeding, host egg tussah silkworm egg is susceptible to mouse, ant, lizard feeding.Other bee-releasing devices such as spherical releaser, bag-type bee-releasing device and box-type bee-releasing device, although can protect parasitic egg from attack, also there is the problem that space is little, not anti-sun exposure, under the weather condition of high temperature in the south, strong sun exposure, can cause bee-releasing device internal temperature too high, affect the emergence of parasitic wasp.For the long parasitic wasp of oviposition early stage, such as flat-bellied wasp, prior art is more unfavorable to its application, flat-bellied wasp will mate first after emergence, supplementary nutrition promotes ovarian development, generally emerges after 3 days and just starts to lay eggs, if weather condition is poor during this period, can affect its pest control effect.

[0037] As attached Figure 1-3 As shown, the parasitic wasp releasing device comprises a top area and a placement area of ​​an integrated design;

[0038] The top area includes a first top plate 1 and a second top plate 2, the top of the first top plate 1 and the top of the second top plate 2 are arranged at an angle through a first fold 4, and both sides of the first top plate 1 and the second top plate 2 are connected to side sealing plates 3;

[0039] The placement area includes a first side panel 5, a second side panel 6, a third side panel 7, a fourth side panel 8 and a bottom panel 9; a second fold 10 is formed between the first side panel 5 and the second side panel 6, a third fold 11 is formed between the second side panel 6 and the third side panel 7, a fourth fold 12 is formed between the third side panel 7 and the fourth side panel 8, and a fifth fold 13 is formed between the fourth side panel 8 and the first side panel 5;

[0040] The bottom of the second side panel 6 and the bottom panel 9 form a sixth fold 14, and the bottom of the fourth side panel 8 and the bottom panel 9 form a seventh fold 15;

[0041] The bottom of the first top plate 1 and the top of the second side plate 6 form an eighth fold 16, and the bottom of the second top plate 2 and the top of the fourth side plate 8 form a ninth fold 17;

[0042] The first side panel 5 and the third side panel 7 are designed as one piece with the corresponding side sealing panels 3, and the first side panel 5, the third side panel 7 and the middle of the side sealing panels 3 are respectively provided with vertical folds;

[0043] A transverse fold is provided in the middle of the bottom plate 9;

[0044] The parasitic wasp releasing device is provided with an air hole 18 and a releasing hole 19;

[0045] Extension blocks 25 are provided on both sides of the bottom plate 9 , and accommodation holes 26 are provided on the first side plate 5 and the third side plate 7 , and the extension blocks 25 match the accommodation holes 26 .

[0046] The application principle of the above device is: when not in use, the device as a whole is folded into a flat structure through the folds, and the surface is stored and carried, such as Figure 3 When in use, the device is propped up along the folds to form Figure 1-2 In the structure shown, the extension blocks 25 and the receiving holes 26 between the bottom plate 9 and the first side plate 5 and the third side plate 7 are matched and plugged, so that a stable spatial structure is formed for use.

[0047] Some improved technical solutions further include a fixing rod 20, one end of which is connected to the center of the first fold 4, and the other end is connected to a hanging ring 21. The setting of the fixing rod 20 and the hanging ring can make it easier to hang the device itself in the field.

[0048] In some improved technical solutions, a rain cover is fixed on the fixed rod 20, and a storage box 22 is provided on the fixed rod 20. The rain cover can be folded and stored in the storage box 22. Soft plastic cloth is used as the rain cover, which can effectively prevent weather disasters from damaging the device and parasitic wasps in the device.

[0049] In some further improved technical solutions, stabilizing ropes 23 are also connected to both sides of the fixing rod 20. One end of the stabilizing rope 23 is connected to the fixing rod 20, and the other end is fixed to both ends of the first fold 4. The setting of the stabilizing rope 23 can assist in the stability of the device when it is suspended and avoid damage caused by external natural factors such as wind.

[0050] In some improved technical solutions, a transparent observation window 24 is provided on the second side panel 6, through which the emergence of parasitic wasps can be observed in real time, making it easier for staff to control the release time.

[0051] In some specific technical solutions, the release hole 19 is composed of cuts on two adjacent plates at the second crease, the third crease, the fourth crease, the fifth crease, the sixth crease, the seventh crease, the eighth crease, and the ninth crease. There are at least two cuts. The structure is arranged at the crease. The crease is angled after being propped up. The release hole 19 is in a closed state. When the release conditions are met through the transparent observation window 24, the release hole 19 can be opened by directly pressing the release hole 19. The structure is simple and the arrangement is reasonable.

[0052] In some specific technical solutions, the diameter of the air hole 18 is less than 0.5 mm. Reasonable aperture setting prevents the parasitic wasps from flying out too early after emergence, and also avoids the threat of natural enemies to the parasitic wasps.

[0053] In some specific technical solutions, the first top plate 1, the second top plate 2, the first side plate 5, the second side plate 6, the third side plate 7, the fourth side plate 8, the bottom plate 9 and the side sealing plate 3 are all made of paper, and the surface is covered with a plastic film. The paper material is environmentally friendly, easy to degrade and has low cost, and the coating structure can play a good waterproof role.

[0054] The specific usage includes the following steps:

[0055] (1) Prop up the release device through the crease;

[0056] (2) The host eggs parasitized by the parasitic wasp are developed and placed in the placement area of ​​the release device 1-2 days before emergence. After that, the device is assembled and sealed by matching the extension block 25 and the receiving hole 26, and then placed in a cool place at 25°C-30°C for development;

[0057] (3) When the parasitic bees are observed to begin to emerge, honey is added through the release holes 19. When 50% of the parasitic bees have emerged, the release device is taken to the field and all the release holes 19 are opened to release the bees.

[0058] When used for releasing flat-bellied wasps, when it is observed that the flat-bellied wasps begin to emerge, honey is added through the release hole 19. When more bees are observed (about 50% or more of the bees have emerged), the release device is taken to the field after 1-2 days, and all the release holes 19 are opened for release.
